II. BACKGROUND OF THE INVENTION

There are numerous problems presently associated with receiving visitorsat a home or office. When the resident of the home or occupant of theoffice (hereinafter generally referred to as either resident oroccupant) is absent, there is often no message for the visitors, nomeans to leave an interactive message for the resident, and no means toensure that unwanted access is not obtained. Moreover, answering thecall of someone at a door of a dwelling can present certain securityrisks to an occupant therein. This situation can be especiallyinconvenient when, for example, a delivery or repair person arrives andthe resident is not present. When the resident is present, on the otherhand, there are also problems associated with receiving visitors. Somevisitors may be unwelcome, for example, and it is often not evident thata visitor is a threat or an annoyance until after the door is open.

There are many types of systems for receiving a person by an occupant orresident and/or on the behalf of the occupant or resident. Such systemsinclude those disclosed in each of: U.S. Pat. No. 5,148,468 titled “DoorAnswering System”, which issued Sep. 15, 1992 to Marrick et al; U.S.Pat. No. 5,303,300 titled “Security Door Phone Device,” which issuedApr. 12, 1994 to Eckstein; U.S. Pat. No. 5,406,618 titled “VoiceActivated, Hands Free Telephone Answering Device,” which issued Apr. 11,1995 to Knuth, et al.; and U.S. Pat. No. 5,657,380 titled “InteractiveDoor Answering and Messaging Device with Speech Synthesis,” which issuedto Mozer on Aug. 12, 1997. Nevertheless, a need remains for furtherimprovement in such a system.

Each of these components84,92,86,90 of the personal computer 80 may be separately disposed fromthe personal computer and connected, for example, by a switch 88, or mayform part of the personal computer 80 and be disposed in electroniccommunication with a bus of the personal computer 80 within the housingthereof.

A speaker 44 is disposed in electronic communication with the personalcomputer 80. The speaker 44 is not shown as being wireless, but couldbe. Moreover, one speaker 44 is shown, but additional speakers could beused in the system 100. Furthermore, speaker 44 in FIG. 1 is representedas being separate from the personal computer 80, however, the speaker 44could alternatively form part of the personal computer 80.

The personal computer 80 preferably is disposed in electroniccommunication with the Internet. The connection with the Internetpreferably is accomplished by a broadband connection such as aconnection 81 provided by a satellite modem, a DSL model, or a cablemodem, or any combination thereof.

The personal computer 80 also preferably is connected to a publicswitching telephone network (PSTN) 70, which enables communication byand with the personal computer 80 via standard telephone lines.

The personal computer 80 preferably has a battery backup as well as ameans for detecting a loss in electrical power such that, whenelectrical power is lost the battery backup will provide sufficientoperating time for the personal computer 80 to notify someoneresponsible for the maintenance of the system that there has been a lossof electricity. Notification of the loss of electricity can beimportant, since the loss of electrical power can be an indication of aburglary. Additionally, if there is no electricity, then appliances,such as refrigerators, air conditioners, and heaters, cannot functionand significant damage can results if the electrical failure goesundetected for a substantial period of time.

The personal computer 80 runs a software application that includes aDVMS Database Application 82 and graphic user interfaces (GUIs). Thepersonal computer 80, in accordance with the software application,controls communication in the system 100, coordinates multiplecommunication devices in the system 100, and is used to define responsesto prompts and events in the system 100. The DVMS Database Application82 and its uses are described in greater detail below.

The system 100 further includes a wireless router 42 located in theinterior. The wireless router 42 in FIG. 1 is represented as beingseparate from the personal computer 80, however, the wireless router 42could alternatively form part of the personal computer 80. The wirelessrouter 42 is used to establish a wireless network and is disposed inelectronic communication with the personal computer 80.

The system 100 also includes a DVMS module 10 located on the exterior ofthe home or office proximate the door 114. The DVMS module 10 isconfigured for use in the exterior of the home or office, which mayinclude outdoor use in external residential or commercial locations. TheDVMS module 10 is disposed in wireless communication with the wirelessnetwork, including the personal computer 80, via the wireless router 42.

With reference to FIG. 2, the DVMS module 10 preferably includes: avideo camera 22; speakers 12; a proximity sensor 26; a microphone 20; anLCD display 16; a quick connect electrical receptacle 24; and aradiofrequency receiver/transmitter represented by antenna 18. Theproximity sensor 26 activates the camera 22 upon detection of movement,which in turn relays an image or streaming video to the personalcomputer 80 where it is saved by the personal computer 80 in a databasein association with a timestamp. Operation of the system is described infurther detail below.

The DVMS module 10 optionally includes a small portable energy source,such as a battery that is rechargeable via the quick connect electricalreceptacle 24, for portable use as well as for use in the event of apower failure.

The LCD display 16 screen preferably is a low energy screen reducingenergy consumption.

In either case, the DVMS module 10 enables text messaging bya person at the exterior, which in turn enables a private non-audibleconversation to be had and eliminates risks of eavesdropping by apasserby.

The DVMS module 10 also includes a locking mechanism 28 for receipt in amounting holster (not shown). The locking mechanism 28 enables the DVMSmodule 10 to be installed securely wherever holstered, or to be moved tosome other remote location, as desired. The DVMS module 10 thus isportable, much like a cell phone, and can be securely mounted andquickly connected to an electrical source.

It is anticipated that there could be multiple entrances to the home oroffice and, similarly, multiple DVMS modules similar to DVMS module 10of FIG. 2 could be utilized, each disposed in wireless communicationwith the wireless network via the wireless router 42.

The system optional includes one or more DVMS transceivers 60. The DVMStransceivers 60 is configured for use in the interior of the home oroffice. As illustrated in FIG. 1, a DVMS transceivers 60 may be disposedin wireless communication with the wireless network, including thepersonal computer 80, and the DVMS module 10, via the wireless router42. Additionally or alternatively, a DVMS transceivers 60 may beconfigured to wirelessly communicate directly with the DVMS module 10,thus bypassing communications through the wireless router 42.

With reference to FIG. 3, each DVMS transceiver 60 is portable and, likethe DVMS module 10, the DVMS transceiver 60 communicates by short-rangeradiofrequency transmissions. The DVMS transceiver 60 includes: speakers62; a microphone 63; an LCD display 66; a quick connect electricalreceptacle 65; and a radiofrequency receiver/transmitter represented byantenna 68. The DVMS transceiver 60 optionally includes a small portableenergy source, such as a battery that is rechargeable via the quickconnect electrical receptacle 65, for portable use as well as for use inthe event of a power failure. The DVMS transceiver 60 further includes amute switch 61, which cuts-off the microphone 63, thus assuring a userof the DVMS transceiver 60 that a visitor can be monitored using theDVMS transceiver 60 without inadvertently sending an audible signal fromthe user.

The LCD display 66 screen preferably is a low energy screen reducingenergy consumption. The LCD display 66 preferably comprises a touchscreen and can be used is used to send and receive text similar to akeypad. Alternatively, or in addition thereto, the DVMS transceiver 60includes a keypad 64. In either case, the DVMS module 60 enables textmessaging by a user of the DVMS transceiver 60 with a person at theexterior using the DVMS module 10, which in turn enables a privatenon-audible conversation to be had and eliminates risks of eavesdroppingby a passerby.

The system 100 further includes one or more remote peripheral devices.Such devices generally include video phones 72; in-car communicationsystems such as the well known ONSTAR system 74 currently found in GMcars; telephones 76; cell phones 77; personal computers 78;smartphones/personal digital assistants (PDAs) 79; and other similarcommunication devices. Each remote peripheral device is configured forelectronic communication with the personal computer 80 via at least thePSTN connection 70 or the broadband connection 81.

As mentioned above, the personal computer 80 runs a software applicationthat includes a DVMS Database Application 82 and graphic user interfaces(GUIs). The software application is configured and maintained by anadministrator, who defines users thereof. The users in the system 100are referred to as “occupants” reflecting their relation to the home oroffice.

Preferably, the occupants have various levels of access to the softwareapplication, depending on the privileges set by the administrator. Theadministrator may also set a level of security under which the system isto operate, particularly with respect to connections made using remoteperipheral devices.

Other examples of configuration settings of the software applicationthat are determined by the administrator include: aliases for a declaredoccupant such as, e.g., “Daddy” or “Momma”; passwords to access thesoftware application; access codes to actuate the electronic lockcontrolled by the computerized controller; a number or other identifierthat corresponds to an occupant's name; and at least one telephonenumber by which an occupant can be reached. The administrator alsopreferably defines a preferred hierarchy of storage of audio and videodata, the location and number of backup devices, and whetherreplications of the database are to be kept.

Additionally, when setting up the software application, theadministrator chooses, inter alia: a prompt for greeting a visitor;chooses an announcement that is to be given over a speaker within theinterior when a visitor arrives; a prompt for requesting informationfrom a visitor; a request instructing a visitor as to their choices inleaving a message or contacting a declared user; and the action that isto be performed by the computerized controller based on the input by thevisitor.

The administrator also tailors the security/premise monitoring responseby, inter alia: designating telephone numbers that the computerizedcontroller calls when, for example, there is a loss of power; anddesignating telephone emergency numbers (e.g., telephone numbers for thepolice, the fire department, relatives, private security companies) thatthe computerized controller calls when an emergency is detected. Thecomputerized controller also conducts self checks to confirm that allthe components of the system are operational and keeps a log of the selfchecks, and the computerized controller preferably calls one or moredesignated numbers when a self check indicates a failure or otherwiseimproper operation.

The software application also can be configured to play background musicor videos at different times of the year and/or different times of theday to reflect seasonal holidays, birthdays, and events. For instance,on Halloween the administrator may wish to have scary music and howlsissuing from the DVMS module for receiving a person at that time.Furthermore, utilizing the computerized controller, the administratorcan choose to use default prompts for interacting with a visitor orcreate customized prompts.

As hardware is added, such as the number of the DVMS modules and DVMStransceivers, the administrator can update both the network to includethe additional devices and the computerized controller to accommodatethe additional devices.

The software application also is configured to send voice, text, andvideo messages via email. The administrator can further set up redundantsubsystems of the system 100.

The system 100, in use, enables secure and effective monitoring andinteracting with a visitor at a residence or business, including, interalia: the detection of the presence of a visitor at the exterior of thehome or office via the proximity sensor 26, the interactivecommunication with the visitor, whether an occupant is present or absentfrom the home or office, the enablement of automated entry into the homeor office by the visitor, and personalization of the process ofreceiving a visitor.

An exemplary method of use in the system 100 includes greeting andcommunicating with visitors of a business or residence. In accordancewith the method, the presence of a visitor is detected via the proximitysensor 26 of the DVMS module 10, where the DVMS module 10 is mounted ator near an entrance to the business or residence. Upon the detection ofthe visitor by the proximity sensor 26, a message is communicated to thepersonal computer 80 from the DVMS module 10 indicating the detection ofa visitor at the entrance. A recording is actuated by the personalcomputer 80, and the recording is stored in a computer-readable mediumsuch as a database along with a beginning time-stamp. The arrival of avisitor is broadcast over a speaker within the home or office, such asspeaker 44. An occupant can view the visitor on a display on the DVMStransceiver 60 or on a display of the personal computer 80, and theoccupant can initiate a conversation at any time. The DVMS module 10issues a greeting to the visitor and instructs the visitor to select anumber from the keypad 14 of the DVMS module 10 in order to designatethe occupant being visited. The entered number is communicated from theDVMS module 10 to the personal computer 80, where the softwareapplication confirms that the number corresponds to an occupant “y” whois “officially” present. An error message is generated if no individualcorresponds to the number entered by the visitor. If no individualcorresponds to the number entered by the visitor, then the visitor isprompted to select and press another number on the keypad 14 againdesignating the occupant being visited. The method then lists thechoices again.

While this is going on, the door may be answered at any time, therebyresetting the software application to look for another visitor. Thesoftware application keeps track of the number of times a wrong numberis entered and can generate a variety of responses to pranks, includingcalling the police, issuing warnings and/or a loud noise, or justthanking the visitor and asking him to return another time.

If appropriate, when the number designated by the visitor matches anoccupant who is officially on the home or office, the speaker broadcaststhat the visitor is here to see occupant “y”. Occupant “y” can signalthe personal computer 80 to take a message, or occupant “y” may chooseto use the DVMS transceiver 60 to speak directly with the visitor, oroccupant “y” can answer the door.

If appropriate, the DVMS module 10 issues a prompt stating that occupant“y” is not available and asks the visitor if they wish to speak tooccupant “y” or to leave a message.

If appropriate, at any time the software application can initiate a callto occupant “y” via a remote peripheral device for communication betweenoccupant “y” and the visitor, and the software application can recordboth sides of the conversation between occupant “y” and the visitor. Theoccupant can view the visitor or initiate a conversation, as theoccupant desires. A visitor never knows where the occupant is, unlessthe occupant tells the visitor of the occupant's location. A visitoralso never knows if the occupant can be contacted, or if the occupanthas just instructed the application to take a message. Using the methodthe conversation or messages can be relayed to the selected occupantwithout the visitor ever knowing where the location of the occupant.Only the occupant can disclose such location to the visitor as desired.

If the visitor elects to leave a message, then the method prompts thevisitor to begin his message and then, optionally, offers him a chanceto review and approve his message. The message or call is stored incomputer readable medium, such as database, by the personal computer 80in association with a beginning timestamp and an ending timestamp alongwith the occupant's mailbox number. At the end of the call or message,the software application can issue a closing statement and return tobackground music, if programmed to do so.

When the visitor departs, and is out of the range of the proximitysensor 26, all recording is stopped and saved in the database record,along with an ending timestamp. The occupant “y” can selectively sort toview the entire recorded visit, or just the message.

If the proximity sensor 26 indicates that there is another visitor, themethod cycles back to the greeting step.

If the system has an electronically actuated lock, then the method alsomay include the steps of checking the number entered by the visitor todetermine if it is a valid access code. The electronically actuated lockmay be unlocked by entering an access code either at the DVMS module 10or remotely therefrom. If the number is valid, then the lock isactuated, and if the number is not valid, then a prompt is maderequested that the code be re-entered. Optionally, the prompt mayfurther request a number be entered that corresponds to one of theoccupants if assistance is needed and, if an occupant is selected, thencalling the selected occupant. The method also may include tracking howmany times the wrong code is entered; checking if the maximum allowednumber of wrong entries have been made; and, when the maximum number ofwrong entries is reached, either automatically calling a designatedparty and/or removing access privileges.

An occupant preferably has the option of remotely entering the accesscode, thereby actuating the electronically actuated lock, or instructingthe GUI database application to go to a new high security level, whereinthe lock cannot be accessed and notifying the visitor that the accesscode is not operational.

In the method, upon the entering of a valid access code assigned to adeclared occupant, the software application optionally notifies theadministrator or his designated representative that the declaredoccupant has now entered the home or office. The administrator wouldknow who the individual should be. The administrator thus can confirm,by remotely viewing the recorded video, that the actual person whoentered the access code is the declared occupant, and/or make afollow-up telephone call to the home or office. The system 100 alsoprovides the options of allowing the visitor to converse with theoccupant, leaving a message, or calling a remote peripheral device forcommunication with the occupant when he is either not present or isunavailable. The entrance is recorded and time stamped for sorting orviewing either in real time or at a later date.

The system 100 further enables the administrator or a declared occupantto, at any time, to turn on a camera and view images, access therecorded the video images, or post a video image from a remoteperipheral device to computerized controller including associatedcomponents.

The system 100 preferably is inherently extensible in both form andfunction and is designed so that the system can be expanded to includemultiple peripheral devices, both in direct and indirect communicationwith the computerized controller. Due to the use of the computerizedcontroller and its interconnectivity, the disclosed system 100 can beconfigured to accommodate communications having a range of complexity.

As will be apparent from the foregoing, the system 100 provides anaudio-video communication and answering system that provides real timecommunication between an exterior of a business or residence and aninterior of the business or residence as well as a location remotelylocated to the business or residence.

As will be apparent from the foregoing, the system 100 provides anaudio-video communication and answering system that provides real timecommunication between two or more rooms at a home or office and a remotelocation.

As will be apparent from the foregoing, the system 100 provides anaudio-video communication and answering system that provides the abilityto leave messages at a centralized location from a local or remotelocation.

In addition to the foregoing description of a method, FIG. 4 shows ablock diagram illustrating an example of the use of a system of theinvention as a door answering and messaging system at a residence.Furthermore, FIG. 5 shows a block diagram illustrating an example of theuse of a system of the invention as a door answering and messagingsystem at a residence, wherein the system includes an electronicallyactuated lock. In the example, an occupant is attempting to gain accessto the home or office.

As will now be apparent, systems in accordance with the inventionachieve one or more of the foregoing benefits and features yet remainintuitive and easy to use.

In addition to the foregoing, it further is anticipated that, in certaindeployments of the invention, voice recognition would be useful,particularly when the system enables access to a home or office. Voicerecognition adds another layer of security, and can be used tofacilitate those individuals who are unable to press a keypad.Similarly, image recognition of faces, eyes and fingerprints can also beincluded in the system for authentication, security, and access. Thesoftware application thus alternatively utilizes voice recognitionand/or image recognition.

Furthermore, while no camera is shown located within the home or office,any number of cameras could be utilized on the interior.

It will also be appreciated that a business may be a tenant locatedwithin a building shared by other businesses. A DVMS module for thebusiness thus would be utilized on the exterior of the business, i.e.,at the “front door” of the business, which would be located within theinterior of the common building.

In variations of systems of the invention, it should further be notedthat one or more devices having the functionality of DVMS modules couldbe utilized in the interior for securing entrance to a room or group ofrooms.

Thelistener port 2205 for down loading audio files is port 5998. The camera210 has access to the audio files in a network-shared folder having adesignated path 2220. When a greeting/verbal response is triggered bythe motion sensor 220, the file is read from the shared folder 2220.Audio files received by the command computer 240 from the camera 210 aresaved in the audio capture folder 2218. The received audio files can beaccessed by the client, pocket PC 260, or cell phone 277, as well as thecommand computer 240. The door reset time 2216 is a parameter thatdesignates the length of time in seconds that must pass after the motionsensor 220 no longer detects a visitor before a recording is stopped.The door audio record timer 2212 is the length of a visitor's message inseconds. The default video archived frames 2209 is the number of imagesor frames that are saved as an archived file. The archived video file2216 can be played back at various speeds. The archived video loop framerate 2216 is in frames per millisecond. Recall that the camera iscapable of generating 30 frames, or 30,000 frames per millisecond. Thisfeature 2216 allows the video to be slowed down. If the administratorwishes to cut off archiving audio files, the administrator can selectthis in box 2213. If the administrator wishes to cut off archiving videofiles, the administrator can select this in box 2209. The audio filescan be turned off completely by using the audio playback parameter 2215.The DVS application 242 can be set to send a message to a cell phone oranother computer. The phone email trigger 2207 sets this parameter, andthe email address is entered into phone email address parameter 2207.The DVS enables different greetings/verbal responses to issue dependingon pre-set criteria. The time of day is one criterion. As shown in FIG.10, there are three audio files: “cats.wav” 2208 a, “creek.wavn” 2208 band “dracwelcome.wav” 2208 c, each of which will be triggered dependingon the time of day. Pairs of boxes 2210 a are set from 7 to 12, textboxes 2210 b are set from 13 to 17, and text boxes 2210 c are set from18 to 6. At 13 hours, or 1 PM, the greeting switches from “cats.wav”2208 a to “creek.wavfl 2208 b, and at 6 PM the greeting switches from“creek.wav” 2208 b to “dracwelcome.wav” 2208 c.
